Effluent Disposal Report

4.0 FINDINGS

All the field information and test results collected during our site investigation and
detailed in this report, including any site plans, log and data sheets together form the
basis of our recommendations for this Land Application Facility.

The soil profile encountered during our investigations, and as reported, was
reasonably and acceptably consistent across the proposed development, and within
our expectations from regional experience and correlation with The Qld Dept of
Mines/Energy Geology Sheet 9445/1999 (Gympie).

The Qld Dept Mines/Energy Geology Sheet 9445/1999 describes the geology as Late
Triassic-Jurassic, Duckinwilla Group, Myrtle Creek Sandstone.

The proposed Land Application Area is on a partially exposed 15-20% southeastern
slope with neighbouring vegetation consisting of grasses and trees.

~ The landform was recorded as natural and partially disturbed.
Slope configuration across the proposed site is determined to be linear planar.

Slope stability problems were not evident during our investigations and expert
evaluation deemed unnecessary.

The susceptibility to flooding from groundwater is low and the indicative drainage
was recorded as imperfect to poor.

No water table was encountered on the day of our site investigation. .
Cobbles and/or boulders in soil profiles are sometimes common and unfortunately we

cannot predict their size or frequency. It has also been our experience that these
floaters can be extremely difficult to excavate with conventional equipment.
